To all whom it may concern: 7

Be it known that I, L UIsE WELLING- 'roN, a citizen of the UnitedStates, a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, administratrix ofithe estate of HmvmiWELLINGTON, deceased, late a citizen of the. United Statesand late aresident of the cityof New York, borough of Manhattan, in tlrecounty andState of New York, who in hislifetime did invent a new and ImprovedBump, dohereby declare the following to be a full, clear, and exactdescription. I

The. object of the invention is to provide a new and improved pump, moreespeclally designed foruse in wells, mines and other places from whichwater or other liqu d s to be raised to a desired he'i"ht, and arrangedto insure raising of tf'e water or otherliquid at a minimum expenditureof power, "to prevent binding of the revolv ng lifting devices, toreduce destruct ve v bration to a minimum, and topermlt convenientremoval 01 the lifting devices for repairs or other purposes without'disturblng the pump cylinders.

In order to produce the desired result use is madeof a pump cylinderprovided with a sectional lining, each section havinga deflector, ashaft extending centrally 1n the said cylinder and passing through thehubs of deflectors, an impellers secured to the shaft and alternatingwith the said deflectors.

For deep Wells or mines use 1s made oi pump units, one above and out ofvertical alinen ent with the other, the lower end of the cvlinder of onepump unit bein connected by an angular pipe ioint With t e upper end ofthe cylinder of the next lower unit, and the motor for the lower pumpunit is mounted on a bracket adjustab y'mounted on the lower end of thecylinder of the unit next above to permit of swinging the bracket to oneside and with it the motor to per-mit rem valpfthe lifting devices fromthe cylinder of this particularpump unit.

A practical embodiment of theunven't on is represented in theaccompanylngdravvforming a art of this specification, in which siinila'riiai'ac'ters of reference Indrca'te corresponding parts in all theviews.

Figure l is a s de elevation o i the, uinp made of 'as'eries of unitsand as applie and with parts shown'in section; Fi 2 is a sectionalplanview of the same on t 1e line 2-2 of Fig. l and showing the motor forthe lowermost pnmp unit swung to one side to permit removal of :thelifting devices of this pump unit; Fig. 3 is an enlar ed sectional sideelevation oi the lower en of a um unit, the section being on the. line33 of Fig. 4; Fig. 4:- is a sectionalplan view of the saine on the line4-4 of Fi 3; Fig. 5 is a sectional side elevation of tfie upper end of apum unitand its connection with the next to lowing unit; Fig. 6 is aside elevation of a pump formed ofa single unit; and Fi 7 is a sideelevation of part of the cylin er lining carrying the deflectors.

The pump illustrated in Fig, 1, consists of a series of pump units A,A','A locate ,one above the other and of such aggregate height topermitlifting water from a Well to a desired place of discharge. The,ump illustrated in" 6 is formed of a single pump unit A. lach of thepump units is provided with a cylinder B provided with an internalliningmade in sections C, each provided at its lower endxwith tongues Cfitting into correspondinglyshaped cut-out portions C in the upper endof the next following section, so that the sections are rigidlyconnected with each other, as will be readily understood by Fig. 7. Thelowermost lining section C is rovided with cutout portions or seatsC geeFig. 3) engaging lugs D formed interiorly on the foot D screwed orotherwise se I cured to the lower end of the e'ylinder B. By thearrangement described the linin is supported in the cylinder B and isheld against turning therein.

In each of the lining sections 0 is secured or integrally formed adeflector C provided with Wings C which extend throughout the height or,the deflector, and each wing C is curved and has the upper and lowerends in vertical alinelnent, asplainly indicated in Fig. 3. The wings Cextend radially from a hub Cf in which is mounted to turn a sleeve Ehaving a polygonal bore fitting ontoa corres ondin ly shaped shaft Fdisposed centr li y in the cylinder B. On the shaft-F are securedimpellers G alternating with the deflectors C each impeller G beinprovide with two oppositely dispose spiral blades G extending from a hubG having a polygonal bore in which fitsthe shaft F so that when thelatter is rotated a rotary motion is given to the correspondingimpellers while the deflectors C remain stationary.

By the arrangement described the liquid forced upward by an impeller Grpasses between adjacent wings C of the deflector C next above so thatthe swirling motion given to the liquid by the impeller is graduallychanged into a quiet movement during its upward passage between thewings C of the deflector C, and the liquid is taken up at the upper endof the deflector C by the spiral blades G of the next following impellerG above. The upper and lower ends of the sleeve E of each deflector Cextend slightly beyond the corres onding upper and lower ends of the hub6 thus forming bearings for the corresponding ends of the hubs G of theimpellers G to keep the adjacent ends of the blades G and the wings Cslightly spaced apart, as will be readily understood by reference toFig. 3. By this arrangement any sediment that may be in the liquid isnot liable to clog or lodge between adjacent impellers G and deflectorsC. I

The lower end F of the shaft F is made round and is journaled in a stepD forming part of the foot D, and the said lower end is provided with acollar F resting on the step D to support the shaft F (see Fig. 3). Theupper end F of the shaft F is also made round (see Fig. 5) and extendsthrough a stufling box H held in a tubular ofl'set I of an angular jointor pipe connection I connecting the upper end of the cylinder B of oneunit with the lower end of the cylinder B of the next following unitabove, as plainly indicated in Figs. 1 and 5. The top of the upper end Fof the pump shaft F terminates in a coupling member J mounted to turn ona ball bearing K held on the support L attached to the top of theofi'set I. The coupling member J is engaged by a coupling member N heldon the lower end of a shaft N of a motor N of any approved construction,preferably, however, of electrical type. The motor N is mounted on abracket 0 having a hub O engaging the lower end of the cylinder B of thenext pump unit above, and the said hub O is preferably made in sectionsconnected with each other by clamping bolts 0 to permit of securelyclamping the hub O in position on the cylinder B. When the bolts 0 areloosened the bracket 0 can be swung around on the cylinder B (see Fig.2) to disconnect the coupling member N from the coupling member J and toallow of lifting the shaft F and with it the impellers G and the liningC with the deflector C out of the corresponding cylinder B withoutdisturbing the position of the latter. The angular olfset I is providedon the top with a short pipe I to which is bolted or otherwise fastenedthe lower end of the next following cylinder B above, as plainlyindicated in Figs. 1 and 5. This joint I carries a step I for the lowerend of the shaft F of the next following unit to turn in, and the saidjoint I is also rovided with lugs I engaged by the seats 8 at the lowerend of the lowermost pipe lining section C of the next following unit,as will be readily understood by reference to Fig. 5.

It will be noticed that by the arrangement described the cylinders B ofsucceeding pump units are out of vertical alinement and are connectedwith each' other by the joint I to provide sufiicient space for thebracket. 0 and the motor N employed for driving the corresponding shaftF. The oifset I of the joint I is provided with a lining I having anangular partition I through which extends the upper end F of the shaft Fto prevent the liquid from passing into the oflset I, as will be readilyunderstood by reference to Fig. 5. I

By the arrangement described any number of units may be readily joinedtogether without taking up much lateral space and any desired number ofpump units may be connected with each other to raise the liquid to thedesired height.

It will further be noticed that in case the lining C is worn out it canbe readily removed from the cylinder B and replaced by a new one, and incase the impellers G or the deflectors C b'ecome defective they can beremoved from the cylinder to be replaced by new ones.

It is further understood that as no set screws, splines or similarfastening devices are used for fastening the impellers G to theshaft F,the center of gravity of the .revolving lifting devices coincides withthe center of the shaft F and an easy running of the pump is the result.

In practice the several motors N are connected for simultaneous controlfrom a single point.

In case the pump is formed of a single unit as shown in Fig. 6, then theoffset I is provided with a goose neck outlet P for discharging theliquid to a suitable place of discharge, the vertical member of thegoose neck P forming a bearing for the hub O of the bracket 0 to allowof swinging the bracket and the motor N into disconnected position thesame as above described rela tive to the pump made of a number of unitsHaving thus described my invention, I claim as new and desire to secureby Letters Patent:
